From 3a848f632f86f1602094e6172cdc05c048042d7a Mon Sep 17 00:00:00 2001 From: Andi Kleen Date: Sat, 16 Apr 2005 15:25:06 -0700 Subject: [PATCH] x86_64: Make kernel math errors a die() now There were no reports about the previous warning for FPU exceptions in the kernel, so make it a die() now. Also improve the error messages slightly.
